The emails have been pleading and plaintive.

“Listen, you know I love you,” a Sept. 6 missive read, adding, “I will always love you.”

Another, on Aug. 30, was even more heartfelt.

“I truly mean it when I say that I will always love and appreciate you.”

As recently as last week, the emotions continued to flow.

“I really do love you,” the email gushed. “I KNOW I JUST WON THE ELECTION!”

The writer in question? Donald J. Trump, who has peppered his pleas for donations with declarations of ardor for his followers in fund-raising pitches of late.

And while Mr. Trump’s tendency toward loving remarks to his supporters dates back years, the pace of such statements has intensified as the campaign rolls toward its conclusion and as he rails against Kamala Harris, whose campaign has made a point of emphasizing “joy” and “good vibes.”

In the last nine days, Mr. Trump’s email blasts have told prospective donors he “loves” them at least 10 times, sometimes promising that his passion had nothing to do with his requests for money.
